Powerworks SC or JRSC BBK w/ 10.2 CR.. which is better for a DD auto?

Ok, so after a long 3 years of saying I was going to stay NA, I have finally decided to go FI cuz I am sick of my friend with his stock RSX-S talking about my car lol. I want to get a Powerworks SC but obviously they are going to be hard to come by now, especially for an automatic. The other option I was thinking about is a JRSC BBK. I have FR2 cams already and cam gears so I figure I can dial out the overlap of the cams as best as possible since they aren't that much more aggresive than the stock cams.

A few questions:
1) If I found either kit for a manual focus would I be able to install it on my automatic?
2) If I went with the JRSC, would it be safe to increase the compression ratio to about 10.2 so I get a little extra power?
3) Would the FR2 cams be ok with either setup?
4) What other options do I have?

I've heard the PW has got much more power than the JRSC, and the PW has the potential for future upgrades....but again, I'm not sure because I'm new like you to FI. Also, I've heard it's difficult to find a PW for the ATX because they don't make them anymore.

Pw Sc

I've been running the PW SC with my Stage 2 Cams in and no problems for the past year now. As for the compression i do not know if it would be safe. I would suggest the PW for the extra powe, you'll be happier in the end

Yea, that seems to be the case with a lot of FI kits for the ATX. I know the PW kit will make at least 200whp while the JRSC you would be lucky to get 170. That's why I am thinking about going that route but also increasing compression to 10.2:1. Therefore the increased compression will give me a little bump in power.

I like the ProCharger kit because you can get an Intercooler with it... :D I saw one on Ebay for pretty cheap....

Not sure of it's compatibility with the ATX though...

Yea, the Procharger looks like a great unit too! Kind of pricey, like the PW kit. JRSC w/ BBK and raised compression would prob cost just as much as the PW or Procharger though, so I think that option is out (unless I can find one used for cheap). Quick question, anyone know if the M62 blower from the SVT JRSC kit would fit on a standard zetec?
